This paper proposes a method for evaluating the work of manufacturing workers using MediaPipe as a risk factor for musculoskeletal diseases. Recently, musculoskeletal disorders (MSDs) caused by repeated working attitudes in industrial sites have emerged as one of the biggest problems in the industrial health field while increasing public interest. The Korea Occupational Safety and Health Agency presents tools such as NIOSH Lifting Equations (NIOSH), OWAS (Ovako Working-posture Analysis System), Rapid Upper Limb Assessment (RULA), and Rapid Entertainment Assessment (REBA) as ways to quantitatively calculate the risk of musculoskeletal diseases that can occur due to workers' repeated working attitudes. To compensate for these shortcomings, the system proposed in this study obtains the position of the joint by estimating the posture of the worker using the posture estimation learning model of MediaPipe. The position of the joint is calculated using inverse kinetics to obtain an angle and substitute it into the REBA equation to calculate the load level of the working posture. The calculated result was compared to the expert's image-based REBA evaluation result, and if there was a result with a large error, feedback was conducted with the expert again.

As the occurrence rate of terror and hazard is increasing throughout the world, GSA, DoD, and FEMA are proceeding a study about mitigating the damage of terror. Korea is no more a safe place from the terrorist's threat, so we need to make measures against them. In this study we developed modified RVS System by revising some items to adjust the system to the domestic condition and conducted a risk assessment on several tall buildings in Korea. By using IRVS system which is developed by DHS, we also carried out the risk assessment. Comparing the results between RVS with IRVS, we performed terror risk evaluation of tall buildings. Through risk assessment of several tall buildings, we analyzed key factors of each scenarios and suggested the mean value of each items, so we would like to help the counter-terrorism in the design phase.

UAV (Unmanned Aerial Vehicle) images can be exploited for rapid forest fire damage assessment by virtue of UAV systems' advantages. In 2019, catastrophic forest fire occurred in Goseong and Sokcho, Korea and burned 1,757 hectares of forests. We visited the town in Goseong where suffered the most severe damage and conducted UAV flights for forest fire damage assessment. In this study, economic and rapid damage assessment method for forest fire has been proposed using UAV systems equipped with only a RGB sensor. First, forest masking was performed using automatic elevation thresholding to extract forest area. Then ExG (Excess Green) vegetation index which can be calculated without near-infrared band was adopted to extract damaged forests. In addition, entropy filtering was applied to ExG for better differentiation between damaged and non-damaged forest. We could confirm that the proposed forest masking can screen out non-forest land covers such as bare soil, agriculture lands, and artificial objects. In addition, entropy filtering enhanced the ExG homogeneity difference between damaged and non-damaged forests. The automatically detected damaged forests of the proposed method showed high accuracy of 87%.

GPI (Group Pollution Index) using 29 indicator groups of Korean benthic macroinvertebrates was proposed in 1992, a higher category taxa-level index developed for rapid field assessment of organic water pollution. This study was performed to revise the assessment scheme of GPI based on taxonomic performance and ecological information accumulated since 1992. The original GPI was renamed SBMI (Simple Benthic Macroinvertebrates Index), and SBMI was based on saprobic valency of 26 indicator groups composed of higher category taxa (mainly family ~ phylum) excluding some genus or species-level taxa. SBMI revealed highly significant correlation with concentration of 5-day biochemical oxygen demand ($BOD_5$) (correlation coefficient r = 0.78, n = 569 sites), total suspended solids (r = 0.69), and total phosphorus (r = 0.77). Also, SBMI revealed strong correlation with Shannon-Weaver's species diversity (r = -0.85), Margalef's species richness (r = -0.85), and McNaughton's dominance (r = 0.83). Determination coefficient of SBMI to concentration of water quality items and values of community indices such as species diversity was 3 ~ 8 % and approximately 11 ~ 14 % higher than that of GPI, respectively. Correlation between SBMI and water quality factors or community indices such as species diversity did not reveal much difference compared to that of species-level indices, such as BMI (Benthic Macroinvertebrates Index) and ESB (Ecological Score of Benthic Macroinvertebrates). SMBI is a simple-qualitative index with higher category taxa easily identified, and is applicable for rapid field assessment of water environment impairment.

This study was performed to assess functions of 10 man-made wetlands in Gunsan City, Jeollabuk Province by means of RAM (Rapid Assessment Method), a technique recommended by Ramsar Convention to appraise wetlands. The assessment of the wetlands value found Gunsan reservoir to have the highest function points while Bukchosan reservoir was estimated to have the lowest function among the wetlands surveyed. By detailed factors of valued 10 man-made wetland, the wetlands were found to function most favorably in terms of vegetational variety and as habitat for wild animals. They need to have more improved functions as habitats for fish and amphibians reptiles, for preservation and betterment of water quality as well as for supplement of underground water, though. From the assessment of vegetational naturalness of the surveyed reservoirs, Gunsan reservoir turned out to be the most favorable wetland from the viewpoint of vegetation science whereas, however, Anjeong wetland was rated as the lowest in the assessment of vegetational value due to simplicity in its vegetation and lots of dangers in its neighborhood threatening its vegetation and ecology. The assessment of vegetational values for Gunsan, Gongchang, Daewi, Bukchosan, Anjeong, Geumgul, Changan and Chuksan reservoirs showed the same orextremely similar results as RAM function assessment. Geumsan reservoir only, however, featured the opposite result.

Environmental Impact Assessment(EIA) was first formally established in the Korea in 1981. Subsequently there has been a rapid growth in EIA activity, and over one hundred fifty environmental impact statements are now published in Korea each year. Although EIA now has almost 20 years of history in the Korea, elsewhere the development of roles and practice is more recent. Development is moving apace in many countries, including the Japan and the EU Member States. Such progress has not been without its problems, and a number of the current issues in EIA-scope of the assessment, the relative roles, the quality of assessment and monitoring and auditing after decision, and so on- are highlighted. So the purpose of this article is to reform the EIA roles and process, in extending the scope of activity, and assessing effectiveness. This article suggested improving the effectiveness of project assessment, widening the scope: stretegic environmental assessment, and extending EIA to project design process, environmental monitoring and feedback system.

Objectives: This study examined the use of health impact assessment (HIA) as a tool for intersectoral collaboration using the case of an HIA project conducted in Gwang Myeong City, Korea. Methods: A typical procedure for rapid HIA was used. In the screening step, the Aegi-Neung Waterside Park Plan was chosen as the target of the HIA. In the scoping step, the specific methods and tools to assess potential health impacts were chosen. A participatory workshop was held in the assessment step. Various interest groups, including the Department of Parks and Greenspace, the Department of Culture and Sports, the Department of Environment and Cleansing, civil societies, and residents, discussed previously reviewed literature on the potential health impacts of the Aegi-Neung Waterside Park Plan. Results: Potential health impacts and inequality issues were elicited from the workshop, and measures to maximize positive health impacts and minimize negative health impacts were recommended. The priorities among the recommendations were decided by voting. A report on the HIA was submitted to the Department of Parks and Greenspace for their consideration. Conclusions: Although this study examined only one case, it shows the potential usefulness of HIA as a tool for enhancing intersectoral collaboration. Some strategies to formally implement HIA are discussed.

This study aims to compare six observational methods for assessing arm- and hand-intensive tasks, based on literature review. The comparison was conducted in viewpoints of body regions, force/external load, motion repetition, other factors including static posture, coupling, duration/break, pace, temperature, precision task, and final risk or exposure level. The number of risk factors assessed was more, and assessment procedure was more complex than the observational methods for assessing whole-body postural loads such as Ovako Working Posture Analysis System(OWAS), Rapid Upper Limb Assessment(RULA), and Rapid Entire Body Assessment(REBA). Due to these, the intra- and inter-reliabilities were not high. A past study showed that while Hand Arm Risk Assessment Method(HARM) identified the smallest proportion of the work tasks as high risk, Strain Index(SI) and Quick Exposure Check(QEC) hand/wrist were the most rigorous with classifying most work tasks as high risk. This study showed that depending on the observational technique compared, the evaluation factors, risk or exposure level, and evaluation results were different, making it necessary to select a technique appropriate for the characteristics of the work being assessed.

우리나라는 경제성장과 더불어 건축물의 형태 및 용도, 재료가 다양해지고 첨단화 되고 있는 반면에 도심 곳곳에 노후화된 건축물 밀집 지역들이 자리잡고 있다. 이러한 노후화된 도시는 재해로부터 상당히 취약하며, 특히 화재 발생시 방내화성능이 신축 건물에 비하여 현저히 낮아 화재가 인근 건물로 확대 되어 도시화재로 발전 될 위험성이 높다. 따라서 본 연구는 도시화재위험성 평가시스템 구축을 위하여 도시화재의 발생 위험성과 화재경계지구의 실태 및 우리나라 도시화재 사례의 전파과정을 살펴보고 일본 건축연구소의 "도시화재 시뮬레이션 모델"에 불티의 비산 모델을 추가하여 구축된 평가 모델을 이용한 실화재 사례에 대한 위험성 평가를 실시 하고자 하였다.
